TITLE: Meta-analysis of the efficacy of immune checkpoint inhibitors in the treatment of NSCLC with different KRAS genotypes
摘要: 目的 评价免疫检查点抑制剂(ICIs)用于鼠类肉瘤病毒癌基因(KRAS)基因不同分型非小细胞肺癌(NSCLC)的疗效。方法计算机检索PubMed、theCochraneLibrary、WebofScience、Embase、中国知网、万方数据、维普网,收集ICIs单药或多种ICIs联用或ICIs联合传统化疗(试验组)对比传统化疗(对照组)用于NSCLC的随机对照试验(RCTs),检索时限为建库至2023年4月1日。筛选文献、提取数据和评价质量后,采用RevMan5.4软件进行Meta分析、敏感性分析和发表偏倚分析。结果共纳入7项RCTs,合计5980例患者。Meta分析结果显示,试验组患者的总生存期(OS)[HR=0.79,95%CI(0.72,0.87),P<0.00001]、无进展生存期(PFS)[HR=0.63,95%CI(0.50,0.80),P=0.0002]均显著长于对照组,且试验组KRAS突变型[HR=0.63,95%CI(0.53,0.75),P<0.00001]、KRAS野生型[HR=0.87,95%CI(0.78,0.98),P=0.02]患者的OS,KRAS突变型[HR=0.58,95%CI(0.43,0.78),P=0.0003]、KRAS野生型[HR=0.68,95%CI(0.47,0.99),P=0.04]患者的PFS均显著长于对照组;按不同治疗方案进行亚组分析的结果显示,试验组使用一、二线治疗方案,单用ICIs,使用ICIs联合传统化疗的KRAS突变型患者的OS,以及试验组使用一线治疗方案的KRAS突变型、KRAS野生型患者的PFS均显著长于对照组(P<0.05)。敏感性分析结果显示,本研究所得结果较稳健。发表偏倚结果显示,本研究存在发表偏倚的可能性较小。结论ICIs用于NSCLC患者的疗效显著,且无论是否发生KRAS突变,NSCLC患者都同样受益。
ABSTRACT: OBJECTIVE To evaluate the efficacy of immune checkpoint inhibitors (ICIs) in the treatment of non-small cell lung cancer (NSCLC) with different KRAS genotypes. METHODS Retrieved from PubMed, the Cochrane Library, Web of Science, Embase, CNKI, Wanfang data and VIP, randomized controlled trials (RCTs) about ICIs alone, combined use of various ICIs or ICIs combined with traditional chemotherapy (trial group) versus traditional chemotherapy (control group) for NSCLC were collected from the inception of the databases to April 1, 2023. After screening literature, extracting data and evaluating quality, meta-analysis, sensitivity analysis and publication bias analysis were conducted by using RevMan 5.4 software. RESULTS A total of 7 RCTs involving 5 980 patients were included. The results of the meta-analysis showed that overall survival (OS) [HR= 0.79, 95%CI (0.72, 0.87), P<0.000 01] and progression-free survival (PFS) [HR=0.63, 95%CI (0.50, 0.80), P=0.000 2] of trial group were significantly longer than those of control group; furthermore, the OS of KRAS mutant type [HR=0.63, 95%CI (0.53, 0.75), P<0.000 01] and KRAS wild type [HR=0.87, 95%CI (0.78, 0.98), P=0.02], PFS of KRAS mutant type [HR= 0.58, 95%CI (0.43, 0.78), P=0.000 3] and KRAS wild type [HR=0.68, 95%CI (0.47, 0.99), P=0.04] in the trial group were all significantly longer than in the control group. Subgroup analysis by different treatment regimens showed that the OS of KRAS mutant type patients receiving first- and second-line treatment regimens, using ICIs alone and those receiving ICIs combined with traditional chemotherapy as well as PFS of KRAS mutant type and wild type patients receiving first-line treatment regimens in the trial group were all significantly longer than in the control group (P<0.05). Sensitivity analysis results indicated that the findings of this study were robust. Publication bias results showed that the possibility of publication bias in this study was small. CONCLUSIONS ICIs show significant efficacy in NSCLC patients, and NSCLC patients benefit equally regardless of whether KRAS mutations occur.
